My present invention relates more especially to windows for use in various types of build- 1ngs.

An object of the invention is to provide a window structure admitting of a variety of oblique positions of the sash for Ventilating and cleaning, the structure in all oblique settings being secure, and in the conventional setting thereof being at least as secure and more rattleproof than windows of conventional construction, the sashes of which have only sliding adjustment.

Another object is to provide a construction of the above type involving simple, inexpensive parts, rugged in construction and easily assembled, installed and manipulated by the occupant or tenant for various settings thereof, all without the need for mechanical skill, or the use of tools, or the likelihood of loosening parts or scraping the paint from the window sash or frame.

Another object is to provide a window sash construction of the above-type which may'be readily and conveniently substituted at relatively small expense for the conventional window sashes of existing buildings, without the need for expert carpenters service.

According to a feature of the invention a conventional sash is used, slidable in the window frame as a unit with lateral sheet metal track members guided by the grooving of the window frame. The sash has a pivot or trunnion mount in the lower ends of said tracks, and one or more links connecting one or both sides of the sash to the associated track to limit the forward pivoting of the sash about its trunnion mount.

According to another feature, the link is pivoted at both ends but has a slide block mount at one end, preferably at the track end, to permit the forward and return pivoting movement of the sash. The link may be of such length and so correlated with the elements it connects as to permit setting the sash at proper angle for ventilation or, if desired, may be of such length and so correlated as to permit setting the sash at proper angle for convenient cleaning of the outside of the pane from` within the building.

According to another more specific feature, two links are provided at one, but preferably at each of the sides of the sash, each link slidable at one end along the track and pivoted at the other end to the side of the sash. The shorter of the links, determining the extreme Ventilating position of the sash, is readily releasable at one end thereof to permit further forward pivoting of the sash for convenience in cleaning the outside of the pane from within the building.

According to another feature, both the longer 5 link and the shorter link have a common pivot mount at the sash, from which pivot the shorter link is readily removable by a convenient resilient pivoting fit.

Another feature is the use of a sheet metal 10 angle plate presenting a ledge protruding from the sides of the sash for cooperation with the track, an associated latch serving to lock the sash to the track when in closed position.'

In the accompanying drawings in which are 15 shown one or more of various possible embodiments of the several features of the invention,

Fig. l is an elevation of the window in closed position,

Fig. 2 is a view in longitudinal cross section 20 through the sash with parts broken away.

Figs. e, 5, 6 and '7 are transverse sectional 25 views taken respectively on lines 4--4, 5-5,y 6-6 and 1-1 of Fig. 2,

Fig. 8 is a view in longitudinal cross section, taken on line 8--8 of Fig. 4,

Fig. 9 is a View in transverse cross-section, 30 taken on line 9 9 of Fig. 8, and

Figs. 10, l1, 12, 13 and 14 are transverse sectional views on a smaller scale, showing various alternative settings of the two sashes in a window frame.

Referring now to the drawings, there is shown in Fig. 1 a conventional window-frame F having therein the usual two sashes S, which, however, as will appear more fully hereinafter, are of widths somewhat smaller than conventional 40 for the frame, the intervening elements presently to be described, compensating for the difference in width.

Referring more particularly to Figs. 2 and 4 to 7, inclusive, each window sash S has trun- 45 nion pins 20 protruding laterally therefrom near the lower end thereof and bearing in metal blocks 2l slidable with the sash in the conventional runways 22 of the window-frame. 'I'he blocks are rigid with sheet metal track mem- 50 bers 23 lining the runway of the window frame and movable along said runway in the sliding movement of the sash.

The forward pivoting movement of the sash about its trunnion pins Z0 is limited by means 55 now to be described. For this purpose, as best shown in Figs. 3 and 6, a sheet metal link 25 is pivoted by means of rivet 26, at one end thereof to a sheet metal slide block 21 near the lower end of the track and slidable longitudinally therealong. The track has ridges 28 thereon to confine enlargements 29 on said slide block. The upper end of link 25 is pivoted to the sash by means of a screw 30 protruding laterally from the sash. By this arrangement it is clear that as the window sash is pivoted forward about its trunnion mount 20, the slide block 21 at the lower end of the link 25 will slide upward. The track 23 is formed with a lug 3| either cut out or soldered or brazed to the track serving as a stop vfor the slide block, to limit the forward pivoting movement of the sash, in the present instance, to a position best shown in Fig. 14 convenient for washing the outside of the pane from within the building.

In addition to the link 25 set forth, a second and shorter link 35 is provided at one side, but preferably at both sides of the vwindow-sash, said link pivoted at its lower or inner end, as best shown in Figs. 3 and 5 by means of rivet 35' to a slide block 36 near the upper end of the track 23, all in manner identical to the slidev block connection of link 25.

The outer o-r upper end of the shorter link 35 also has a pivot connection to the side of the sash. The latter pivot connection, which is preferably on the same stud 30 which aflixes the upper end of link 25, is preferably of the construction best shown in Figs. 3, 8 and 9. According to this construction, the link 35 has a pair of parallel slits 31 determining a tongue 38 therebetween, the upper end of which is widened at 39 and notched at 40, to determine the lower half of a circular aperture, the upper part of which appears at 4I and is rigid with the body of the link. The head of the stud 30 is grooved at 42 so that the aperture in the link 35, by virtue of the resilience of tongue 38 will readily snap over the head 42 of the stud to form a secure friction hold thereover, which, however, permits the slight rotary displacement incurred in pivoting movement of the sash.

It is, of course, understood that the longer link 25 may be at one side of the sash and the shorter link 35 at the opposite side of the sash, cr that both links, as shown, may be at one and the same side of the sash, but preferably two pairs of the links are used, one pair at each side of the sash.

It is clear that as the window sash embodying both the longer link 25 and the shorter link 35 is pivoted outward from normal position, the two slide blocks 21 and 36 slide upward along the track 23 until slide block 3B strikes the abutment 43 in the track by which the latter is connected to the counterweight cord 44. In that position, best shown in Figs. 3 and 11, the sash is in a preferred Ventilating position.

When it is desired to wash the outside of the window-pane, the shorter link 35 is simply pushed outward away from the sash to release it from friction stud 30, whereupon the sash can be pivoted forward considerably farther to the limiting position, shown in Fig. 12, in which the slide block 21 is arrested by stop 3|.

To restore the sash to position, it is obvious that the forward end of the shorter link 35 is rst snapped back in position about its pivot 30 and the sash is pushed back into the window frame about its trunnion pins 20, in which action the two slide blocks 36 and 21 will move downward along their tracks and the links will become confined in superposed position between the sides of the sash and the tracks, as best shown in Figs. 4 and 5. 5 In order to effect a secure t of the sash with respect to the tracks 23, a metallic interlock between said elements is preferably provided. In the specific embodiment shown, the sheet metal track 23 is preferably provided with a 10 unitary reversely bent longitudinal ledge 45 at Y the advanced end thereof, said ledge protruding laterally inward from the side of the window-frame and constituting a sheath. The sash is provided with a sheet metal angle 15 plate 43, having a longitudinal ledge il spaced from the edge of the sash itself and fitting snugly in the sheath 45 on the track 23, as best shown in Figs. 4, 5 and 6. By this arrangement, a secure rattle-proof substantially air- 20 tight connection between the sash and the window-frame is effected. In order to avoid excessive strain on the sheath 45 in pushing the sash back to home position, it is preferred to provide a rearward extension ledge 48 on the track which 25 will take the rearward thrust of the sash, as best shown in Figs. 4, 5 and 6.

While the frictional hold set forth between the sash and the` tracks may be suflicient, it is preferable to provide a positive latch between 30 said elements. One embodiment of such latch is best showcn in Fig. 8. As shown, said latch comprises a loop 53 struck out from the sheath 45 of the track 23 and a hook v5l integral with the upper end of the angle bar ledge 41. The 3,5 angle bar 45 may be longitudinally displaceable along the Window sash to set the latch, for which purpose said angle bar is connected te the window sash by screws 52 through vertical elongated slots 53. The upper end of the angle 40 bar is provided, as best shown, in Figs. 8 and 9 with a thumb piece 54 which, when pushed downward sets the latch, and thus locks the sash in the track and window frame, and when pushed upward releases the latch to permit 45 pivoting displacement of the sash. The speciflc thumb piece arrangement, just set forth, is most convenient for the lower sash. For the upper sash it is preferred instead of the thumb piece to use hinged finger pieces 55, as best 50 shown in Fig. 1, and also to connect the upper ends of the angle pieces 45 by a sheet metal cross bar 56 affixed also by screws 51 in vertical elongated slots 58.

It will of course be apparent, that the latch 55 shown is merely illustrative, and that any of a wide variety of latching or fastening instrumentalities may be employed for releasably connecting the sash to the track to afford a rigid sliding assembly when the sa'sh is to be posi- 50 tioned in the manner of conventional sashes.

The mode of use of the sash will be readily understood from the drawings, in connection with the foregoing description, but Figs. 1G to 14 give a pictorial indication of the flexibility e5 of use of the installation.

The setting of Fig. 10 permits of burglarproof locking of the lower sash without preventing Ventilation through the upper sash shown in Ventilating position. Fig. 11 shows 70 both sashes in Ventilating position, and is effective for liberally admitting air, but excluding rain and to a large degree excluding noise. Fig. l2 shows the lower sash in position for washing, although of course, that position may be 75 adopted also for ventilation, as shown in Fig. 14, with respect to both the window sa'shes. Fig. i3 shows the lower sash set in position for Ventilating purposes with the elimination of the auxiliary ventilator commonly used in substantially that position for such purpose.

While the drawings show the conventional wooden sash, it will, of course, be understood that the invention is also applicable to metal sash windows.

It will also be understood that while a long and a short link are preferably used in the specific manner and for the purpose set forth, it is within the scope of thel broader claims to use but a single link or a single pair of links to admit but of one limiting position, for the sash reasonably suitable both for ventilation and for washing the exterior pane.

While the invention is of course suitable for new building constructions, it is applicable to existing buildings as well, without involving the slightest alteration or rebuilding of the conventional window-frame construction thereof. All that is necessary is to replace the window sashes by other sashes of otherwise conventional construction, but slightly narrower, with their associated tracks and links, the weight cord being attached to the tracks in the manner previously l set forth.

It will thus be seen that there is herein described apparatus in which the several features of this invention are embodied, and which apparatus in its action attains the various objects of the invention and is well suited to meet the requirements of practical use.

As many changes could be made in the above construction, and many apparently widely different em'oodiments of-this invention could be made without departing from the scope thereof, it is intended that all matter contained in the abovev description or shown in the accompany- 'ig drawings shall be interpreted as illustrative and not in a limiting sense.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
